An `.ocamlinit` helper to `#require` packages in an OCaml toplevels

nosetup helps you to load the dependencies of your project into your toplevel
of choice (OCaml Toplevel as well as UTOP) so you don't have to #require your
dependencies yourself. It does so by finding your project metadata (even if you
are in a subdirectory, similar to git), parsing it and then using findlib
to load it into your toplevel session.

Currently it supports Merlin's .merlin files, though there is no limitation
of which files could be supported as long as the findlib package names can
be parsed.
